UNITED STATES PATENT CRAWFORD C. LOOMIS, OF ILION, NEW YORK, ASSIGNOR TO REMINGTON ARMS G625- PANY, A. CORPORATION OF DELAWARE.

FIREARM.

Application flled July 29,

This invention relates generally to firearms, and especially to the type of firearm disclosed in the patent J. D. Pedersen, 908,833, Jan. 5, 1909. In said patent there .is disclosed a carrier which is pivoted within the frame or receiver and which acts at its forward end to lock the action bar in its forward position while the hammer is cocked, and at its rear end to prevent operation of the trigger until the action bar is fully forward. ()ne of the objects of my inventlon is to provide means whereby the receivermay be lengthened to accommodate lon er cartridges, while at the same time provi mg for the locking of said action bar as well as the trigger. To avoid the necessity of changing the length of the carrier and to thereby avoid considerable changes in the parts cooperating with the carrier, I provide a membar in the receiver, which member at its forward end acts as an action bar lock and at its rear end co-operates with the carrier to lock the trigger. Thus a carrier and coacting parts of standard size may be employed in the lengthened receiver, and the locking of the action bar and'trigger may be accomplished at the proper time.

Another object of my invention is the provision of means, simple in construction and reliable in operation, for preventing forward movement of the rearmost cartridge when the magazine is being loaded with the muzzle inclined downwardly; and for positively cumming the rim of the rearmost cartridge into guideways in the magazine action bar during rearward movement of the latter,

thereby preventing forward movement of said cartridge by the carrier when the pressure of the follower spring is removed-from said cartridge. I

A further object is to provide a novel form of cartridge stop for regulating the feeding of the cartridges thru the magazine.-

#Still another object is the provision of simple and eflicient means for retracting the firing pin from the cap of the exploded cartridge prior to the unlocking of the breech block.

Another object is to provide a novel combination of an ejector and firing pin wherein a single spring may be employed for maintaining both saidfiring pin and ejector in retracted position.

Another object is the provision of a" 1922. Serial No. 578,436.

As in the Pedersen Patent, 908,883, previously referred to, the barrel 1.is secured to the barrel portion 2 of the frame or receiver, while the butt stock 4 is secured to the stock portion 3 of said receiver. The parts 2 and 3 of the frame or receiver enclose a chamber in which are located most of the working parts of the gun, including the breech block 5. The latter is reciprocable in the receiver and at its upper forward end is provided with an upwardly extendingshoulcartridge der 6 for engaging the recoil shoulder 7 in the forward top portion of the receiver.

For moving the breech block backwardly and forwardly in the receiver as well as for engaging and disengaging the breech block' lug 6 with the recoil shoulder 7, the action bar 8 is employed, said action bar havin secured thereto a forearm 9. As in the aforesaid Pedersen patent, this action bar also forms a magazine and may be designated by the term magazine action bar. The rear portion '10 of said magazine action bar ex-- tends thru an opening in the receiver below the barrel. The breech blockis provided eagues near its forward end with a downwardly ox tending inclined projection '11,'which'projection,when the breech block is in its closed andfbreeched-up position, (Fig. 2).- rests on a shoulder 12 on the rear end of the. part 10 of the action bar, so thatthe shoulder 6 of the breech block is locked in engagement to depress the forward end of the breech block and thereby remove projection 6 from engagemenwith shoulder 7 the action bar 'with recoil shoulder 7. When it is desired 'is drawn rearwardly, whereby an inclined face 13 thereof strikes the forward inclined.

face ofprojection 11 and draws-the breech block downwardly until vprojection 11 .is brought into a'recess formed between face 13 and shoulder 12. The breech block-is now projection 6 arrives in front of shoulder 7,

to the rear end ofr sing by the-top of the receiver until the whereupon furtherforward movement of; the I action bar 'into its fully forward or home position raises the, breech block due to the rear inclined face of projection 11 in cooperation with the. inclined rear surface of i the aforesaid recess in the action bar, whereby the forward end of the breech block is raised so that projection 6 engages recoil shoulder '7 and the breech .block is locked against rearward movement. The bottom of the action bar is provided with shoulders Inn 8' adapted to strike against corresponding stop shoulders 2 1n the lower front portion of the receit'er to limit the forward movement of the action bar. (See Figs. 18 and section 14 of the magazine action bar are hollow to accommodate cartridges. (See Fig. 6.) The section 14 is shown as tubular, as is also a portion 15 extending'forwardly from the rear part of section 10. The forward part of ortion 15 aforesaid is screw threaded exterlorly, as is also the rear portion of section 14. A connecting sleeve 16. is rovided intermediate its length with intenor screw threads, whereby both sections of the magazine action bar may be threaded into said sleeve and thereby connected together. A small. screw 17 is, threaded through sleeve 16 and projects into a hole in the' actionbar section 14, so that the lat-- Both the rear section 10 and the forward removed. Said screw is covered by the fore- I am 9, which is provided on op with two escutcheons 18, 18 (Fig. through osite sides which screws '19, 19 extend into opposite sides of sleeve.16.' Said screws are threaded cartridge carrier 27.

into said sleeve and project into holes in portion of the rear section 10 of the action bar to prevent turning of the sleeve 16 with respect to said rear section until said screws 19, 19 are removed. Associated with each screw 19 is a small locking screw 20 mounted in the corresponding escutcheon and adapted to engage in one of a series of arcuate notches 21 in the head of the corresponding screw 19 (Fig. 4). Said screws 19 may thus be locked in adjusted portion.

A follower 22 in the form of a hollow plunger is mounted in the magazine, said follower being pressed rearwardly by a spring 23. As shown in Fig. 6 said follower is provided with a circumferential shoulder 22 adapted to strike against a corresponding shoulder in the tubular section 15 whereby the rearward movement of the follower is limited. The magazine portion of the action bar terminates rcarwardly in shoulders 24, 24. Forwardly of said shoulders there is provided in the top of the action bar an enlarged slot 25 of sufficient size for permitting the body of a cartridge to pass vertically out of the magazine. Below said slot 25 the side walls of the magazine are curved,

thereby forming a tubular magazine portion which extends forwardly and forms a rearward continuation of the tubular interior .of nagazine portions 14 and 15. That part of the action bar that extends rearwardly of shoulders 24 is slotted vertically, as shown at 26 to accommodate the vertically swinging Forwardly of the shoulders 24 a groove 28 is cut in the floor of the magazine portion of the action bar to accommodate the forward end of the carrier aforesaid. the bottom of said groove forming a shelf or ledge 29. (Figs. 3 and 16.) At the rear end of the enlarged slot 25 are lateral recesses 30, 30, which extend downwardly into the tubular magazine and form a passage for the rim of the cartridge head.

The carrier 27 is pivotally mounted on a sleeve 31 which is mounted in vertical side flanges 38, 38' of the receiver portion 3. A screw 31" is passed thru the sleeve 31 for securing together the parts 2 and 3 of the receiver. as disclosed in the Pedersen patent previously referred to. As in said patent the forward portion of said carrier is rocked upwardly during the initial part of the forward movement of the action bar to feed a cartridge out of the magazine and into lateral undercut guideways 32 inside extensions 33 on the face of the breech block 5. (Figs. 8 and 9.) This swinging of the carrier is caused by a dog 34 carried by the action bar, in coo eration with a cam groove 37 in the side 0 the carrier. Said dog 34 is mounted on one end of a leaf spring 35 which at its other end is secured to the action bar by a screw having a fine thread, the head of said screw being undercut as much as possible to allow greatest possibl bearing surface and thus relieve strain, and the end of the spring is slotted to also relieve strain. As shown in Fig. 13, said sprin is positioned in a groove in one of the si e walls of the action bar and holds said dog projected thru an opening in said wall of the action bar, so that said dog extends into the path of the carrier. When the action bar is drawn rearwardly from its forward position, said dog enters a cam groove 36 in the forward end of the carrier. The floor of said groove is in clined upwardly from the front to the rear thereof so that as the rearward movement of the action bar is continued the dog 34 is cammed laterally onto the adjacent side of the carrier. In Fig. 19 I have shown the walls of said groove curved for cooperation with dog 34, whereby the latter, when in engagement with said groove, steadies the carrier. After the dog 34 is cammed laterally onto the side of the carrier said dog rides along the side of the carrier during the continued rearward movement of the action bar and finally, at or near the end of said rearward movement, said dog snaps into the cam slot 37 aforesaid, so that when the action bar is moved forwardly the forward portion of the carrier is raiwd as mentioned above. The front face 38" (Fig. 23) of the side flange 38' of the receiver portion 3 may serve as a stop to limit the rearward movement of the action bar, said face being shown in Fig. 23 as having a contour suitable for receiving the rear end of the adjacent side portion of the action bar and preventing further rearward movement of the latter.

When the gun is taken down, that is when the. stock assembly is removed from the receiver and barrel assembly, the rearward movement of the action bar is stopped by the engagement of the end 341 of the j magazine action bar 8 which surrounds the dog 34, with the take down screw 31'. It will be noted (Figs. 5 and- 13) that the part 341 surrounding the dog 34 projects some? what beyond the opposite side of the forked end of the magazine'action bar; The engagement of the projecting end 341 'with the take down'screw stops the movement of the action bar before the lockin lug 6 has reached the recess or well 6' (Fig. 2) in the top of the receiver, thus preventing the accidental disengagement of the breech block from the action bar which might occur if the lug 6 reached and entered the well 6'. In prior guns of this type it has been necessary to provide special action bar stopping devices for preventing such an accidental separation of the action bar and breech block, which devices are eliminated by the present invention.

The hammer 39 and the meansfor driving the same a ainst the firin pin 40 are the same as disclosed in the Pe ersen patent I llo to. The drivin means previously referred spring aforesaid takes the form of a coile '41 which. acts upon the head 42 of a rod orplunger 43 connected to the hammer 39.

-"- The hammer is cocked by rearward movement of the action bar and breech block and is held in cocked position by the engagement of the notched forward endof trigger 44 with a catch shoulder 45 on said hammer.

" Said trigger is pivoted at 46' in the stock portion 3 of the receiver and is urged by a spring 47 to position fo'r'holding the hammer cocked. Said spring 47 is shown mounted within a recess-in the trigger 44 and,thru a plunger 48, acts 'on av tail porfrom its rearmostto its forwardposition.

plunger, as shown A spring 53 or spring and he rear end in Fig. 3, interposed between a of lever and the trigger guard 52, tends locked against rearward movement.

I of plunger 43 moves 49 of the carrier.

to raise said rear end and hence to lower the forward end of said lever 50. Assuming the hammer 39 to be cocked and the magazine action bar to be fully forward, the rear end of lever 50 is rocked downwardly by spring 47 acting thru the carrier, whereby the forward end of said lever is raised into the path of the action bar. The latter is therf ply e spring 53 is weaker than thespring 47, so that the latter canovercome the action of spring 53 and lower the rear end of lever 50 as described. If now, the trigger is pulled, the hammer 39 is. driven forwardly by spring 41 and explodes the cartridge in the barrel. D'uring this movement of hammer 39, head 42'of rod or plunger 43 strikes the tail 49 of carrier 27 and raises .the forwardend of said carrier, as shown in Figs. 2 and '3, so that spring 53 can now rock lever 50 out of the path of the action bar. The latter is thereby unlocked. If the action bar now be moved rearwardly, the breech block is retracted and the hammer cocked, as aforesaid, during which time the head 42 out of contact with tail The latter is prevented from dropping by the locking lever 50 in cooperation with the bottom of the action bar and also by the shelf or ledge 29 previously described, which shelf comes beneath. the forward portion durin rearward movement of the action bar. he dog 34 is meanwhile cammed laterally by the floor of groove 36, as previous ly described, and at or near the end of the rearward movement of the action bar said dog snaps into cam slot 37 ,so that when the hammer.

of the carrier action bar is moved forwardly the carrier 1s raised. Raising of the carrier causes a toe 54 on the bottomthereof to cam against a toe 55 on the rear end of lever 50, whereby the rear end of said lever is loweretl and the toe 54 of. the carrier is permitted to pass to the front of the toe 55 of said lever. Lowering of the rear. end of said lever and consequent raising of the front end thereof by the aforesaid toe 54'is permitted byja. clearance notch 56 in the action bar, which clearance notch is at that time over the front end of lever 50. When the carrieris raised,

as aforesaid,so tha't toe 54 thereon is in front.

of toe 55 on the lockin lever, a rearwardly extending hook 57 on t e carrier'is beneath aprojection 58- on the trigger so that the latter: and consequently the hammer, are locked against operation. Said hook 57 of the rEarrier remains beneaththe projection the trigger to. lock-the latter against operation unt1l the forward movement of the action mer 39 is locked in cocked osition until the breech block 5 is full orward and engaged with recoil sh'oul er 7. After the dog 34 moves out from under the shoulder 59 of the carrier during forward movement of the action bar the carrier drops slightly until the toe 54-thereon strikes the front side of toe 55' on the locking lever, the upper end of said carrier thereby clearing the body portion 5' (Fig. 9) of the breech block, but

the hook 57 aforesaid is still in position for preventing operation of the trigger.- Further dropping of said carrier during the forward movement of the action bar is prevented by lever 50, since the toe 55'on the rear end of said'lever is behind the toe 54 on the carrier and the bottom of the action' bar prevents the forward end of lever 50 from moving -upwardly.- When, however, the action bar clears the forward end of the locking lever, at which time the breech block is fully ,home and the action bar is fully forward, the "ring 47 raises the tail 49 of the carrier, an thru the co-operating toes 54 and 55 on the carrier and lever, respectively cams the rear end of said leverv downwardly so that the toe 54 on the car'- rier passes over the carrier returns to' normal position wherein the top of the hook 57 thereof is opposite a depression in the trigger. The latter can be now operated to release the At the samev time, the forward end of lever 50 is in the path of the action bar, being so held by spring 47 thru shoulder 59 of the carrier, whereby rearward movement of the action bar is prevented until the cartrid e in the barrel is fired or until the rear en of lever 50 is raised manually. The bottom of the frame or receiver is provided with a slot 60 forwardly of the trigger guard 52, thru which slot a porbar is completed, whereby the ham-- the toe 55 on the lever and tion of the lever is adapted to-project, .as'shown in Fig. 2. Access to the rear portion of said lever is thus permitted so that the latter can be moved manually to unlock the action bar.

To permit the insertion of cartridges into ing is closed by .a door 62, which is pivoted to the'side of the magazine and is urged by spring plunger-s 63 to closed position. Suflicient friction is provided so that the door will remain open against the action of the springs so that the necessity of continually overcoming the action of the spring or fighting the door is obviated. This friction may be provided by a curved portion 64 of the door in cooperation with the spring lungers 63, as shown in Fig. 14. When the door is in closed position, the spring plungers 63 bear against a flat surface 65 on the door, but as the door is moved away from closed position the curved portion 64 is brought into contact. with the plungers 63, whereby the door is held open until closed by the operator. In loading, the operator holds the cartridge against the inclined rear end of the opening 61 with the forward end of the bullet in contact with the rear end of the follower 22, or. of a cartridge in the magazine as the case may be, and pushes forwardly. The follower 22 and any cartridges in the magazine forward of the cartridge being inserted are thereby pushed forwardly and the body of the cartridge which is being inserted strikes the rear beveled edge 66 of the loading door 62, thereby deflecting said door. The forward movement of the cartridge being in-' serted is continued until the rim thereof coincides with clearance grooves (57-67 in the loading port 61, whereupon the cartridge can be pressed inwardly into the magazine. Assuming the magazine to be empty prior to loading a cartridge, the spring-pressed follower 22 forces said cartridge intothe rear position of the magazine so that the head of said cartridge abuts the rear magazine shoulders 24. The next car- I tridge is then pushed forwardly against the action of the follower 22 and, when entered into the magazine, assumes a position H115 mediately in front of the first cartridge.-

The third cartridge loaded assumes a position ahead of the first cartridge but behind the second cartridge, and so on. Thus, the first cartridge is at the rear of the magazine, the second cartridge at the front thereof, and the succeeding cartridges occupy successive positions between said secon. and first cartridges. \Vhen the loading door 62 is open it acts as a stop to prevent retraction of the action bar thru more than a limited distance. Retraction of the action bar with door 62 open brings said door into contact with the end of the receiver before the action bar is moved more than a short distance. I For preventing forward movement of therearmost cartridge in the magazine, which ample, the gun is being loaded with the muzzle tilted downwardly, and for raising the r m of said cartridge Into the recesses or guideways 30-30 during the rearward movement of the action bar, I provide a dog '68, which dog is pivotally carried by the action bar near the rear end thereof. The

'movement might otherwise occur if, for ex- Y forward portion of said dog projects thru 1 an opening in the side of the action bar and extends into the rear part of the magazine portion thereof. A spring .69 interposed between the action bar and the rear end of dog 68 urges the forward portion of said dog into the magazine. The forward portion of the dog 68,-which ma be termed the cartridge dog, is provi ed with a face 70 inclined laterally from top tobottom and from the front of the dog toward the rear thereof as shown in Fig. 21. To 1 the-rear of said face 70 is a shoulder 71, behind which shoulder is another face 72 which inclines laterally from the top to the bottom thereof. Assuming the magazine to be empty and a cartridge to be inserted therein, the spring-pressed follower 22 in the magazine moves said cartridge rearwardly so that the rim of said cartridge strikes the inclined face 7 0 of the cartridge dog 68 and cams the front portion of said dog laterally into arecess 7 3 in the adjacent side wall of the receiver. As the head of the cartridge approaches the rear end of the magazine the rim of the cartridge passes behind the shoulder 71, whereupon the spring 69 rocks the-forward portion of the dog 68 slightly inwardly with respect to the magazine so that the shoulder 71 is brought immediately in front of the rim of the cartridge. 'Forward movement of said cartridge is thus prevented. Should the muzzle of the gun he tilted downwardly when the next cartridge is being inserted into the magazine. the first mentioned cartridge, being held by the dog 68. cannot move forwardly to interfere with the loading of said next cartridge.

\Vhen a cartridge is forced by the spring follower 22 so that the rim of said cartridge lies behind the shoulder 71 on the cartridge dog, said rim rests on the inclined face 72- of said dog. Now when the action bar is moved rearwardly, an inclined shoulder 74 on the outer side of the forward portion of dog 68 strikes an inclined shoulder 7 5 in the recess 73 in the adjacent wall of the receiver, whereby the shoulder 71 is pressed cartridge. During further rearward movement of the action bar the cartridge dog 68 rides for a limited distance upon a straight portion or dwell ofthe recess 73 and then the shoulder 74 of said dog comes into contact with a portion 76 of said receiver which is inclined from said straight portion of said recess to the inner wall of the The raising of the rear end of the rearmost cartridge into engagement with the guidereceiver. The forward portion of the cartridge dog is thereby rocked further inwardly and the inclined face 72 thereof raises the rear end of the rearmost cartridge so that the rim of said cartridge enters the guideways or recesses -3O in the sides of the magazine. While the spring 69 might be utilized to rock the cartridge dog sufficiently for raising the rim of said rearmost cartridge into said guideways, I prefer to employ more positive means for this purpose and have therefore provided the inclined surface 76 for co-operating with the shoulder 74-. of the cartridge dog, as above described.

ways aforesaid is accomplished before the pressure of the follower spring 23 on the rearmost cartridge is relieved by the striking of the next forward cartridge, or of the follower, against the cartridge stopf 7;, t e

which will be described hereinafter. rearmost cartridge were not engaged with the aforesaid guideways prior to the reward movement of the action bar.

' upwardl from the head of the immediatel lieving of the pressure of the follower spring on said cartridge, said cart-rid e would be likely to be moved forward w en brought into contact with the inclined forward portion 78 of the carrier 27 during the rear- How ever, by engaging the rim of said cartridge with said guide-ways before the pressure of the follower spring on said cartridge is relieved, such forward movement of. the cartridge is prevented and the cartridge, upon striking the inclined front portion 78 of the carrier during rearward movement of the action bar, will be cammed further into the guide ways aforesaid. Then, a er the rearward movement of the action bar is completed the carrier 27 is raised during the initial portion of the subsequent forward motion of the action bar and raises the cartridge aforesaid out of the magazine and into engagement with the guideways 32-32 on the face of the breech block so that as the breech block is moved into its forward position the cartridge is inserted into the barreL- To prevent the cartridges immediately ahead of the rearmost cartridge from partaking of the full rearward movement of the magazine action bar, whereby the forward end of the rearmost cartridge is spaced ing cartridge during the final portion of the rearward and the initial portion of the forpreced-' ward movement of the action bar, I provide the cartridge" stop 77. This stop, as shown in Fig. 22, is in the form ofa bell crank lever pivoted at 77 in the receiver. horizontal arm of the cartridge stop 77 extends over a portion'of the magazine and is provided with a nose or projection 79 extending downwardly into the magazine for cooperation with the cartridge therein. The vertical arm of the cartridge stop has a projection or toe 80 extending laterally therefrom and adapted to enter an exterior groove 81 in the ad'acent side of the magazine action bar. spring 82 may be interposed between the horizontal arm of the cartridge stop and the receiver to' prevent any possible vibration of thefsto although this spring may be omittedi desired. The forward face of the nose 79 aforesaid projecting from said horizontal arm is beveled so that when the magazine actionbar is full forward a cartridge contacting with sai nose, will, under the influence of the spring-pressed follower 22, lift said horizontal arm -.and pass under said nose to the rear of the magazine. At this time the groove 81 is opposite the toe 80 on the vertical arm of the cartridge stop so that rocking of said stop to raise the horizontal arm thereof is permitted. Now, if p the action bar'be moved rearwardly, the

beveled end portion 81' of groove 81 cams the toe 80 and vertical arm of the cartridge stop outwardly whereb the horizontal arm The Y Continued rearward movement of the action bar then moves the rearmost cartridge away from the preceding cartridge. The rearmost cartridge is thus separated from the preceding cartridge during the'final portion of the rearward and the initial portion of the forward movement of the action bar,'

thus obviatingcthe danger of exploding said preceding cartridge by the forward end of the rearmost cartridge, and also facilitating moving of said rearmost cartridge out of the magazine by eliminating the possibility of friction between the forward end of said rearmost cartridge and the head of said preceding cartridge. A slot in -the top of the section 10 of the magazine action bar extends forwardly from the en'- larged slot 25 for the purpose of receiving the nose 79 of cartridge stop 77 during the rearward movement of the action bar.

Breech block 5 has slidably m ounted therein thefiring pin 40 and an e ector 83. Firin pin 40 .is mounted in a longitudinal borev m the breech blockf wvhile the e ector 83 is mounted ina 'roove in the side of the breech block. "-"Sai ejector has a foot or projection 84 extending laterallyfrom the front end thereof and extending into a recess in the front of the breech block, the front of said recess being open so that said foot 84 may be projected beyond the face of the breech. block. Said ejector foot 84, which shoulders cut into the ejector and the firing pin while the spring 86- bears at one end against the plunger aforesaid; and at its other end against a portion of the breech block. A spring-pressed pivoted extractor 87 of ordinary construction is carried by the forward portion of the breech block and the hooked forward end of said extractor proects beyond the forward face of the breech lock for gripping one side of the rim of a cartridge. One of the side extensions 33 on the face of the breech block 5 is cut away to permit the extractor hook to form part of the corresponding guideway 32.

The upper portion of the opposite guideway which is adjacent the foot 84 of the extractor is beveled or inclined upwardly and is curved to conform somewhat with the rim of the cartridge, as disclosed in the patent to Pedersen, 963,171, July 5, 1910. It will thus be seen that the ejector foot 84, W11 moved forwardly, can readily push the 21(- jacent portion ofv the carriage forwardly, so that the entire cartridge turns about the extractor hook as a pivot and is ejected thru an opening 88 in the side of the frame or receiver. v

.VVhen the cartridge is ready to be fired, its rim is held on one side by the extractor hook and on the other side by the straight portion of the opposite guideway 32. When the trigger'is pulled, the hammer falls and drives the firing pin 40 forward against the action of the spring 86 and the cartridge is thereby exploded. Upon retracting the action bar, the breech block 5 is moved rearwardly as aforesaid, and the ejector is brought against a shoulder 89 on the stock portion 3 of the receiver, whereby the ejector foot 84 is thrust forward and the cartridge is ejected through the aforementioned opening 88. The ejector foot 84, being in the upper portion of the breech block, imparts a downward, as well as a sideways motion to the are preferably made in two pieces to acilicartridge. Both the ejector and firin pin tate assembling in the breech-block and to permit a more solid breech block to be used. For withdrawing the firing 'pin from the primer. cap as the action bar is moved rearwardly, to permit the breech block to be readily moved downwardly out of engagement with the recoil shoulder 7 in the top of 'the receiver, I provide a retractor 90 slidably mounted in the side of the breech block. Said retractoris provided with lat- I extending shoulders 91, 91 between whic shoulders is received a foot 92 project ing downwardly from the forward portion of the firing pin 40. An extension 93 of the retractor projects downwardly and for-- 'wardl and is adapted to be struck by a shoul er 94 on the action bar before the latter has moved rearwardly suflicientl to exerta downward force on the breec block,

whereby the retractor is drawn rearwardly and in turn moves the firing pin rearwardly out of engagement with the primer of the cartridge prior to downward movement of the breech block. A spring 95, hearing at one end against a portion of the breech block and at its other end against the retractor, tends to move the latter forwardly, said forward movement of said retractor being limited by the striking ofa shoulder 96 thereof a ainst a pin 97 at the side of thebre ech b ock. The upper portion of said pin coacts with a shoulder 98. on theejector' to limit the rearward movement thereof. The 'retractor spring 95 is coiled around a rod 99 which abuts at one end against the breech A slidable safety lock 107 is shown forpreventing operat1on of the trigger, said lock having a notch 108 for permitting the trigger to be operated when the lock is moved to the proper position. -This lock, being conventional and well known in the art, need not be described herein.

,It may be desired at times to retract the action bar after the latter has been moved forwardly far enough for dog 34 to pass from under carrier shoulder 59 but before said action bar has moved forwardly completely. To permit such retraction of the action bar I have shown the part 59 of the carrier rovided with a cutaway portion terminating in an inclined shoulder 27' for co-operation with dog 34. If the action bar has been partiall moved forward so that dog- 34 has move from under shoulder 59, the shoulder 27 permits the action bar to be retracted immediately without the necessity of completing the forward movement of the action bar, and the dog 34, in cooperation with shoulder 27, simply raise the carrier slightly during such retraction of the action bar, until said dog passes rearwardly into cam groove 37. A cartridge may thus be ejected by moving the action bar rearwardly before the forward movement of the action bar has been completed.

While I have shown the various features of my invention applied to the type of firearm disclosed in the Pedersen Patent 908,883, above referred to, it will be understood that myinvention is not limited to any particular type of firearm. Also-it is apparent that the specific structureherein disclosed may be modified and varied in numerous ways without departing from the spirit of my invention.
